S-90911A815 3/8"-16 x 1 1/4" ASME B18.9, SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional tensile strength of 120,000 PSI ensures reliable performance under heavy loads, reducing the risk of bolt failure in demanding applications.
• Superior corrosion resistance from zinc plating extends service life and maintains integrity in harsh or outdoor environments.
• Secure anti-rotation design with a square neck prevents loosening under vibration, providing consistent clamping force.
• Easy installation and alignment due to the standard 82° countersink angle and flat head, allowing for a flush, professional finish.
• Wide compatibility with UNC coarse threading and Class 2A fit facilitates quick assembly and interchangeability with standard components.
• High durability from Rockwell C25 hardness and Grade 5 classification ensures long-term reliability in industrial settings.
• Full threading offers versatile fastening depth and uniform stress distribution along the entire bolt length.

Professional Applications & Engineering Value

These Grade 5 Plow Bolts are engineered to address critical challenges in heavy machinery and equipment assembly. Constructed from zinc-plated steel, they resist rust and wear, making them ideal for agricultural implements, construction equipment, and snowplows where exposure to moisture and debris is common. The square neck design locks securely into mating parts, preventing rotation during operation and reducing maintenance needs. With UNC coarse threads and a Class 2A fit, these bolts ensure quick, precise installation, minimizing downtime. The flat head with an 82° countersink provides a smooth surface, eliminating protrusions that could cause damage or safety hazards. This combination of high tensile strength and robust materials delivers reliable performance in high-stress applications, enhancing the longevity and safety of industrial assemblies.
